Overview
The Glenamoy is a spate river, and that’s the first thing to know before you book a day on it: it fishes best not in settled weather but in the two or three days after a flood, as the peat-stained water drops back to a fishable level. The anglers who do well here watch the rain in the catchment, not the calendar – levels rise and fall fast.
The river (Irish: Abhainn Ghleann na Muaidhe) rises in the upland townlands of Glencalry and Barroosky and runs roughly 23 km west through Glenamoy village before meeting the Muingnabo River at Gortacragher, where the two form Sruwaddacon Bay on the Atlantic. Most of that course is across blanket bog: the river threads the Slieve Fyagh Bog and the Glenamoy Bog Complex, both Special Areas of Conservation, so the surrounding land is protected peatland rather than farmland or forestry.
At an average elevation of just 8 metres, the lower river floods hard. After heavy rain it can turn from a quiet stream into a torrent that has swept away cattle and bridges – on a night of storms in August 1933, three arches of the old bridge washed out under the pressure of the rising water. Treat the river with respect in spate; this is not a place to wade casually after rain.
Angling
The Glenamoy carries a reasonable run of grilse and sea trout from July to September, on top of its salmon. The fishery is state-owned and leased to the Glenamoy Community Angling Association (GCAA), which manages access and conservation. The salmon and sea-trout season runs from 1 May to 30 September, and catch-and-release has applied in recent seasons – check the current rules when you buy your licence, as bag limits change year to year.
The GCAA has put real work into the banks: an extensive bush-clearance programme, stiles and footbridges along the length of the fishery, and several excavated holding pools. Near New Bridge they’ve also built a wheelchair-accessible fishing pool – a genuinely rare facility on an Irish spate river, and the reason the Glenamoy is worth knowing about for anyone who’d assumed wild-river fishing was off-limits to them.
Day permits and State angling licences are sold at the Anglers Rest Bar in Glenamoy village. Buy in person and you’ll get current advice on which pools are fishing; ring ahead in peak season.
The river corridor
Away from the pools, the Glenamoy is a quiet walk through classic Erris bog – wide, open, wind-scoured, with waders and the odd raptor over the wetland. Be honest with yourself about what it is: a working fishery in a remote stretch of north Mayo, not a manicured beauty spot. There’s no visitor centre, no café at the water, and little to do here if you’re not fishing or walking the banks. The footbridges and stiles make the banks easy enough to follow, and the peatlands turn deep russet in late summer and autumn, when the low light suits the place best.
The valley has its history too. On 21 September 1922, during the Civil War, a pro-Treaty National Army detachment was ambushed by Anti-Treaty IRA forces here, and the long gun battle that followed is remembered locally as the Battle of Glenamoy.
Practical information
Access to the banks is free; fishing needs a State angling licence and a GCAA day permit, both from the Anglers Rest Bar. The village has a post office and an adjoining petrol station, so you can fuel up and pick up basics, but services are limited – stock up before you come.

- Permits: State angling licence required for salmon and sea trout; day permits at the Anglers Rest Bar.

- Safety: Levels rise fast after rain. Check conditions before heading out, especially in autumn when Atlantic systems are most active.
Getting there and nearby
Glenamoy sits on the R314, roughly midway between Belmullet and Bangor Erris, with the road continuing on towards Ballina to the east.
With time to spare, the Bangor Trail gives a long, rugged walk through the bogs, and inland Ballycroy National Park protects some of the best blanket bog and mountain in the country. North-east of the village, the Céide Fields preserve a 6,000-year-old Stone Age field system under the bog, with a guided tour for €5 – an easy half-day to pair with a morning on the water.
Time your trip to the water, not the dates: come a day or two after rain, ring the Anglers Rest Bar for the permit and the pool report, and you’ll have made the most of one of north Mayo’s quieter rivers.
